How to get json object from specific part of json string?

Question

I want to extract stand array's first index which is located under "allocations" and turn into json object. How can i do that ? doesn't matter if it's from google.gson.JsonObject, org.json or org.json.simple library.

the specific part requested to be turned into json object is also marked.

Json is the following one.
